Big River Dry Backpack
Rugged waterproof storage engineered for paddle sports, motorcycle touring, expedition travel and demanding field environments. Built to protect critical equipment when weather, water and abrasion are part of the mission.
Built for Hard Use
The Sea to Summit Big River Dry Backpack combines the simplicity of a heavy-duty dry bag with an integrated backpack harness for easier movement of equipment between vehicles, boats, staging areas and remote locations.
Constructed from heavy-duty 420D ripstop nylon, the pack provides excellent abrasion and puncture resistance. Double-stitched, fully taped seams and a waterproof roll-top closure provide dependable protection in wet environments.
Operational Features
Waterproof fabric, roll-top closure and fully taped seams protect equipment from rain, spray and wet environments.
Ripstop nylon provides excellent abrasion and puncture resistance for repeated field use.
Triple-coated oval base increases durability and improves water shedding when the pack is placed on wet surfaces.
Streamlined EVA foam shoulder harness with sternum strap and removable 38 mm webbing waist strap.
Strong grab handle and external lash rails make the pack easy to secure to kayaks, motorcycles, vehicles and roof racks.
White TPU interior laminate reflects available light, making equipment easier to identify inside the pack.
Replaceable buckles allow damaged hardware to be serviced quickly without replacing the complete pack.
The ovalized design improves stacking and makes the pack easier to lash securely to equipment.

Load Carrying Guidelines
The Big River Dry Backpack is designed primarily as a rugged waterproof transport pack rather than a technical load-bearing backpack.
Sea to Summit indicates an approximate carrying limit of 20 kg for shorter-distance carries and approximately 12 kg for longer-distance carries, depending on the wearer.
Load comfort and practical carrying limits will vary depending on terrain, distance, equipment configuration and individual wearer.
